1 Thump - I had read that thread today before posting and as mattsz stated there was no resolution. I was hoping someone maybe knew of an aftermarket solution other than Hitchcocks. I have a fork brace on my XS650 and I am convinced of the effectiveness of using one.

I think the superbrace guys were interested but no one could/would send measurements. I just got a UCE-style disc fork for my old bike and would be very interested in a brace, but am probably not the precision kind of guy they'd need for measurements. My caliper is big enough to take the OD of the fork sliders and probably the distance between the inner facing surfaces of the fork, though...maybe I should get in touch with them.

Wonder if they'd make one which bolts into the fender mount bosses and could support a properly-drilled plain aftermarket fender...

Just spoke with Chris at superbrace. He says they have over 250 different fork braces and their is a chance that something off the shelf might just fit. So, he needs measurements: Outer diameter of the fork and 'center to center' measurement i.e. from center of one fork to the center of the other. He said approximate measurements is fine for now.
